DART VADAR can automatically sense and respond to molecular triggers in cells.

During the COVID-19 pandemic, the term mRNA was brought to the public’s attention. It is, however, not a new medical technology, having been identified in 1961.

These mRNA vaccines were developed to generate a full-body immune response in order to protect the human body from the deadly coronavirus and its variants.

Researchers from the University of Cambridge have created a new type of neural implant that could restore limb function in paralyzed limbs.

There have been former attempts at using neural implants to restore limb function, but these mostly failed. This is because scar tissue can envelop the electrodes over time, disrupting the connection between the device and the nerve.

Published 1 hour ago Researchers at Wuhan University of Science and Technology have made a breakthrough discovery that could potentially cure blindness for some people.

Scientists in the US managed to put together a living computer by cultivating over 80,000 mouse stem cells (opens in new tab) (via IT Home) (opens in new tab). One day, the hope is to have a robot that uses living muscle tissue to sense and process information about its environment.

Researchers at the University of Illinois have used tens of thousands of living mouse brain cells to build a computer that can recognize patterns of light and electricity. The team presented their findings at the American Institute of Physics in the form of a computer about the size of your palm.

Physicists at Delft University of Technology have built a new technology on a microchip by combining two Nobel Prize-winning techniques for the first time. This microchip could measure distances in materials at high precision—for example, underwater or for medical imaging.

Because the technology uses sound vibrations instead of light, it is useful for high-precision position measurements in opaque materials. The instrument could lead to new techniques to monitor the Earth’s climate and human health. The work is now published in Nature Communications.

The microchip mainly consists of a thin ceramic sheet that is shaped like a trampoline. This trampoline is patterned with holes to enhance its interaction with lasers and has a thickness about 1,000 times smaller than the thickness of a hair. As a former Ph.D. candidate in Richard Norte’s lab, Matthijs de Jong studied the small trampolines to figure out what would happen if they pointed a simple laser beam at them.

In a recent perspective article published in the journal Science, researchers at the Young-Onset Colorectal Cancer Center of Dana-Farber Cancer Institute emphasized that a better understanding of the etiology of early-onset colorectal cancer (EOCRC) is crucial to managing its increasing incidence worldwide. So, they identified five critical areas for investigating EOCRC biology.

For individuals suffering from drug addiction, certain cues—whether it’s specific people, places or things—can trigger powerful cravings for repeated use.

A new University of Michigan study has identified brain signals, traditionally associated with inflammation, contributing to people’s vulnerability to addiction. With repeated drug use with the same exposure to cues, some individuals develop an inability to control their drug use, even in the face of negative consequences.

The study is published in the journal eNeuro.

A team of geochemists from the Chinese Academy of Sciences, working with colleagues from the University of Hong Kong, Tianjin University and the University of California, has found evidence that suggests much of the oxygen in early Earth’s early atmosphere may have come from rocks. In their study, reported in Proceedings of the National Academy of Sciences, the group conducted lab experiments involving crushing rocks, exposing the results to water and measuring reactive oxygen species that were emitted.

Prior research has shown that Earth experienced what has been called the Great Oxidation Event approximately 2.3 to 2.4 billion years ago. During this time, microbe numbers increased dramatically, as they released oxygen during photosynthesis. But prior research has also suggested that a common life ancestor existed before the Great Oxidation Event, which further suggests that there was some amount of oxygen exposure. In this new effort, the researchers suggest that such oxygen could have come from rocks interacting with water.

The work involved crushing samples of quartz and then exposing them to water, which replicates some of the conditions that existed on early Earth prior to the rise of high levels of oxygen in the atmosphere. Adding water to freshly crushed quartz, the researchers found, led to reactions between the water and newly broken crystals. This resulted it the formation of molecular oxygen along with other reactive oxygen species like hydrogen peroxide. Such species are also known as free radicals and they would have played an important role in the evolution of early life. This is because by damaging DNA and other cell components, the free radicals would have pressured early life to adapt.

While virtually all of the industry is buzzing about AI, accelerated computing and AI powerhouse NVIDIA has just announced a new software library, called cuLitho, that promises an exponential acceleration in chip design development times, as well as reduced chip fab data center carbon footprint and the ability to push the boundaries of bleeding-edge semiconductor design. In fact, NVIDIA cuLitho has already been adopted by the world’s top chip foundry, TSMC, leading EDA chip design tools company Synopsys and chip manufacturing equipment maker ASML.

Industry partners like EDA design tools bellwether Synopsys are chiming in as well, with respect to the adoption of cuLitho and what it can do for their customers that may want to take advantage of the technology. “Computational lithography, specifically optical proximity correction, or OPC, is pushing the boundaries of compute workloads for the most advanced chips,” said Aart de Geus, chair and CEO of Synopsys. “By collaborating with our partner NVIDIA to run Synopsys OPC software on the cuLitho platform, we massively accelerated the performance from weeks to days! The team-up of our two leading companies continues to force amazing advances in the industry.”

As semiconductor fab process nodes get smaller, requiring finer geometry, more complex calculation and photomask patterning, offloading and accelerating these workloads with GPUs makes a lot of sense. In addition, as Moore’s Law continues to slow, cuLitho will also accelerate additional cutting-edge technologies like high NA EUV Lithography, which is expected to help print the extremely tiny and complex features of chips being fabricated at 2nm and smaller.
